Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a passenger conveyor such as an escalator or an electric road, and particularly to a highly safe handrail structure.

It is well known that escalators generally have the configuration shown in FIGS. 1 and 2.

That is, main parts such as a step 1 and a handrail 2 that are arranged in an endless manner and rotate, a balustrade section 3 provided on both sides of the step 1, a handrail frame 4 that constitutes this balustrade section 3, and a balustrade panel. 5 inner deck 6, outer deck 7
All of these components are supported by a sturdy main body frame 8.

The rotating bodies of the step 1 and the handrail 2 are configured to reverse at the terminal end of the passenger conveyor (near a and b in FIG. 1).

Here, the most common cross-sectional shape of the parapet portion 3 is that shown in FIG. 2, and the width dimensions of each are as follows.

Taking an escalator as an example, its effective width is represented by the width of the parapet 3 (to be precise, it refers to the horizontal width 600 mm vertically above step 1), and generally W1 = 12
The 00mm one is called the 1200 type, and the Wl-800mm one is called the 800 type.

In this case, the width W2 of the step 1 on which the passenger rides is approximately 1000 mm (1200 type) and approximately 600 mm (800 type).

On the other hand, the width of the handrail 2 is such that it is disposed outside of the balustrade panel 5 (Wl < W3) because it also runs below the balustrade panel 5.

Also, the width W4 of the main body frame 8 and the outer deck 7. W5 is also on the outside of handrail 2 (W3<W4゜W3゜W5.W4〈W5
), and the total width W5 is approximately 1700 mm.

In this way, the cross section of the passenger conveyor is arranged at a position that does not overlap with respect to the nominal effective width W.

For the conventional passenger conveyor as described above, there has recently been a demand for a new space-saving design that minimizes the overall width W5 and maintains Wl without reducing the transport capacity.

This space-saving concept is rooted in the need to maximize the sales area within the building, and has great economic advantages.

Most recently, to meet these needs.

As shown by imaginary lines in FIG. 2, a body frame 8a has been proposed in which the body frame 8 is moved below the handrail 2, and a configuration in which the overall width W5 is shortened by several tens of millimeters has also been proposed.

This method is an extremely welcome method because it allows the overall width W to be shortened without changing the effective widths (Wl and W2) of the step 1 and the parapet 3, which directly affect the increase or decrease in transport volume. .

In this case, it goes without saying that the running path of the handrail 2 will be affected to some extent, and the conventional width W3 will be shortened, and the handrail 2 will have a parapet panel 5 (as shown in FIGS. 3 and 4). 3 and 4, the width dimension remains as Wl).

The reason for this is that W5 is shortened while widths W1 and W2 remain as they are, so generally such a positional relationship is inevitable.

As described above, the configurations shown in FIGS. 3 and 4, which were determined based on space-saving considerations, have the following extremely serious safety problems.

That is, there is a real hidden danger in selecting the amount of protrusion M1 and M2 of the handrail frame 9 disposed between the handrail 2 and the handrail panel 5a relative to the handrail panel 5a.

First, if M is set to about 10 to 20 mm, there is a problem that children's fingertips may enter the gap g as shown by arrow f1 and get injured. If the passenger (H in Figure 1) travels on a business trip to the outside of the
It is fully expected that a collision like this could damage the equipment, or that the passengers themselves would fall due to the shock of the collision.

Such a dangerous situation is especially serious when the protrusion is small Ml, and in this case, the intrusion of the fingertip as indicated by the arrow f1 and the intrusion of the fingertip as indicated by the arrow C into the rotating body at the inverted portion of the handrail 2 as shown in Fig. 4. Situations such as collisions may also occur.

Note that in the cases of arrow A in Figure 1 and arrows B1 and B2 in Figure 3, the collision occurred when a passenger pulled up luggage, etc., and is not as serious as arrow C in Figure 4. I can say it.

Here, if you try to avoid the situation shown by arrow f, which shows the intrusion of your fingertips, and set the projector M2 (it is difficult for your fingers to enter, as shown by arrow f2), collisions with luggage, etc. will inevitably occur (arrows A2 and B2). It is obvious that this is a cause for concern.

In addition, it can be said that in the collisions along the arrows A1 and B1, since the protrusion Ml is small, the collision shock is also small.

As mentioned above, it has been stated that the recent space-saving balustrade designs shown in Figures 3 and 4 still have safety issues such as intrusion of fingertips and collisions with luggage.

In view of this point, the present invention provides, directly above the parapet panel 5a,
This was done in order to improve the safety of the railing in a so-called space-saving passenger conveyor in which the handrail 2 is disposed directly below or in the vicinity thereof.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 5 and 6, the positional relationship (vertical direction) between the handrail 2 and the balustrade panel 5a is the same as in recent FIG.
A feature of the handrail frame 10 is that the handrail frame 10 has the following characteristics.

Here, the handrail frame 10 has a δ corner 10b slightly wider than the width of the handrail 2, and the slope 1
0a is configured with an angle θ that gradually becomes narrower from this corner 10b toward the balustrade panel 5a.

The device is designed to prevent children's fingertips from entering the gap g (arrow f3), and to guide luggage inward (toward step 1) as shown by the arrow.

In this case, a violent collision like the one shown by the arrow C cannot occur, and even if the luggage etc. collides, it will be guided by the slope 10a, so at least the rotating body (handrail 2)
Dangerous collisions can be prevented.

Note that the amount of protrusion δ of the corner portion 10b is sufficient as long as it can naturally prevent fingertips from entering, and in some cases, as shown in FIG.
The handrail frame 1 has a slightly minus δa corner at 1a, and a large protrusion 11b on the outside of the passenger conveyor.
Even 1 is acceptable.

It is also possible to form a concave surface Z as shown in FIG.

By doing this, it is possible to eliminate problems such as fingers entering the handrail 2 and collisions with luggage.

In addition, the space Q of the handrail frame 11 in FIG.
is used to store a lighting object or its cord.

According to the present invention described above, there is an advantage that the safety of a space-saving passenger conveyor can be improved.
